Original Abstract

This paper shows that mesh density dependency in brittle element lattice models cannot be completely removed by incorporating material mesostructure. This is concluded as a result of a series of simulations of fracturing in concrete using a 2D rigid-body-spring network. In the case of notched beams loaded in three-point-bending (TPB), adding finer grain structure led to a significant reduction in the dependency of the peak force on the mesh density. However, the energy dissipated during the fracture simulation was still affected significantly by the mesh density.
